Many sceptics thought it was impossible to achieve NMI Approval for a Multifunction Electricity Meter designed in a compact DIN rail footprint. In fact many doomsday forecasters predicted electrical switchboard enclosures, distribution boards, riser/cupboard spaces for multifunction metering would have to be increased in size to accommodate larger electrical metering to be in compliance for Energy Meters per NMI M 6-1.

One of the many technical and metrology requirements for obtaining pattern approval and verification from The National Measurement Institute (NMI) for any active-energy electricity meter to be used for trade is for the energy meter to pass the 12KV impulse test.

Electricity meters, energy meters, multi-function metering and any power metering incorporating internal clocks for date/time stamp resolution must comply with NMI electrical metering standards to ensure the clock time does not drift.

NABERS rating for data centre load management and performance has been introduced to encourage improved environmental performance within the commercial built arena, improving innovation and outcomes for reducing energy consumption and reduced green-house gas (GHG) emissions.

Electrical harmonics is an important issue in the modern electrical network, becoming increasingly more important as more switching and smart loads are present.

Today’s world of electricity measurements is important to ensure various levels of readings are accurate, repeatable for data validation, billing accuracy and assurance of data integrity.
